electrons that are closer to the nucleus!..apex//
Helium has 2 core electrons. This is because it has 2 electrons in the innermost energy level (K shell), which are considered core electrons.
Argon has 18 core electrons. This is because the atomic number of argon is 18, and the number of core electrons is equal to the number of electrons in the nearest noble gas configuration, which in this case is neon (10 core electrons), plus the number of electrons in the next energy level, which is 8 for argon.
Core electrons have lower energy levels than valence electrons. Core electrons are closer to the nucleus and are more tightly bound, while valence electrons are in the outermost energy level and have higher energy due to being farther from the nucleus.
Hydrogen has one core electron. Core electrons are those in the inner energy levels of an atom and are not involved in chemical bonding.
Bromine (Br) has 18 core electrons. This can be determined by subtracting the number of valence electrons (7 in the case of bromine) from the total number of electrons in a neutral atom, which is 35 for bromine.
electrons that are closer to the nucleus!..apex//
Core electrons are the inner electrons of an atom that are tightly held by the nucleus and are not involved in chemical reactions. These electrons are typically found in filled electron shells closer to the nucleus.
Germanium has 36 core electrons. Core electrons are the inner electrons that are not involved in chemical bonding.
Germanium has 18 core electrons. Core electrons are the inner electrons of an atom that are not involved in chemical bonding.
Argon has 18 core electrons. This is because it has 18 electrons in total, and the core electrons are the innermost electrons that are not involved in chemical bonding.
Carbon has 2 core electrons. Core electrons are the inner electrons of an atom that are not involved in chemical bonding.
Silicon has a total of 10 core electrons and 4 valence electrons.
it has 2 electrons i think you can tell by subtracting both numbers together
Helium has 2 core electrons. This is because it has 2 electrons in the innermost energy level (K shell), which are considered core electrons.
Cadmium (Cd) has 48 electrons, and its electron configuration is [Kr] 4d10 5s2. This means that the core electrons in cadmium are those in the inner shells, which are the 36 electrons from the noble gas krypton (Kr). Therefore, cadmium has 36 core electrons.
Oxygen as 2 core electrons and 6 valence electrons.
Oxygen has 6 core electrons.
